Spare parts have always been and will probably always be a very capricious topic with accountants and budget planners. Spare parts are just a cost burden on a system until they are necessary.
Over the years Underwriters Laboratories (UL) 1449, Institute of Electrical and Electronics Engineers (IEEE) standard C62.41, and International Electrotechnical Commission (IEC) 61643-1 surge protection terminology has been changing.
Many Ac/Dc power supply manufacturers are not grounding the Dc side of their power supplies. In some cases, the Ac/Dc power supply manufacturer does not offer an option to even ground the Dc side of the power supply. The Ac side of the Ac/Dc power su
The electrical system within any facility is nothing more than a necessary tool that is required to complete just about every task within the facility.
Electrical protection terminology in the 21st century has many names. Lightning Arrester (LA), Surge Protector Device (SPD), Surge Arrester, Surge Suppressor, and Transient Voltage Surge Suppressor (TVSS) are the most common names used.
They have been around since the time of Nikola Tesla, George Westinghouse and Thomas Edison. In many facilities power quality issues are either ignored, mismanaged or misunderstood. At most facilities whenever electrical equipment fails the process i
